Squamous cell skin cancer Squamous cell cancer may occur in undamaged skin. Or, it can occur in skin that has been injured or inflamed. Most squamous cell cancers occur on skin that is regularly exposed to sunlight or other ultraviolet radiation. The earliest form of squamous cell cancer is called Bowen disease (or squamous cell carcinoma in situ). This type does not spread to nearby tissues because it is still in the outermost layer of the skin. Actinic keratosis is a precancerous skin lesion that may become a squamous cell cancer.

- Squamous-cell carcinoma or squamous-cell cancer (SCC or SqCC) is a cancer of a kind of epithelial cell, the squamous cell.These cells are the main part of the epidermis of the skin, and this cancer is one of the major forms of skin cancer. Unlike basal-cell carcinoma (BCC), squamous-cell carcinoma (SCC) has a substantial risk of metastasis. 2  Risk of metastasis is higher in SCC arising in scars, on the lower lips or mucosa, and occurring in immunosuppressed patients.

NCI Dictionary of Cancer Terms Most head and neck cancers are called squamous cell carcinomas, because they begin on the surface layer of the region within the head or neck, where the cells are flat and squamous. Cancer confined to this layer of cells is called carcinoma in situ. When the malignant cells spread into deeper layers of cells, it is called invasive squamous cell carcinoma. Types of head and neck cancer. Learn about different types of head and neck cancer.

Trusted information on medical conditions Have a health concern? Our experts guide you through symptoms, causes, diagnosis, and treatment options. The Second Most Common Form of Skin Cancer. Squamous cell carcinoma (SCC) is an uncontrolled growth of abnormal cells arising in the squamous cells, which compose most of the skin’s upper layers (the epidermis). SCCs often look like scaly red patches, open sores, elevated growths with a central depression, or warts; they may crust or bleed. They can become disfiguring and sometimes deadly if allowed to grow. More than 1 million cases of squamous cell carcinoma are diagnosed each year in the U.S., and (depending on different estimates) as many as 8,800 people die from the disease.

What Causes Basal and Squamous Cell Skin Cancers? Most basal cell and squamous cell skin cancers are caused by repeated and unprotected skin exposure to ultraviolet (UV) rays from sunlight, as well as from man-made sources such as tanning beds. UV rays can damage the DNA inside skin cells.DNA is the chemical in each of our cells that makes up our genes.esearchers don’t yet know all of the DNA changes that result in skin cancer, but they have found that in many skin cancers the cells have changes in tumor suppressor genes. The gene most often altered in squamous cell cancers is called TP53. This tumor suppressor gene normally causes cells with damaged DNA to die.

- Cumulative exposure to sunlight causes most cases of squamous cell carcinoma. Frequent use of tanning beds also multiplies the risk of squamous cell carcinoma; people who use tanning beds are 2.5 times more likely to develop squamous cell carcinoma than those who don’t. But skin injuries are another important source.

What Are Basal and Squamous Cell Skin Cancers? Squamous cell carcinoma in situ, also called Bowen disease, is the earliest form of squamous cell skin cancer. “In situ” means that the cells of these cancers are still only in the epidermis (the upper layer of the skin) and have not invaded into deeper layers. Bowen disease appears as reddish patches.

Squamous cell skin cancer SCC is still sometimes referred to as  epidermoid carcinoma  and  squamous-cell epithelioma , though the use of these terms has decreased. SCC typically initially occurs in the sixth decade of life (the 50s), but is most common in the eighth decade (the 70s). It is twice as prevalent in men as in women. The tumor grows relatively slowly. 2  Unlike basal-cell carcinoma (BCC), squamous-cell carcinoma (SCC) has a substantial risk of metastasis. 3  Risk of metastasis is higher in SCC arising in scars, on the lower lips or mucosa, and occurring in immunosuppressed patients.
